Changing the brake oil in a Pulsar 150 involves a few simple steps. Here's a general guide to help you through the process:
Note: It's always recommended to refer to your motorcycle's manual for detailed instructions and specifications specific to your model.
Gather the necessary tools and materials:
- Fresh brake fluid of the recommended type (check your manual for specifications).
- A small container or a drain pan to collect the old brake fluid.
- A clean cloth or shop towels.
- A wrench or spanner to loosen the bleeder screw.
- A clear plastic tube that fits tightly over the bleeder screw.
Prepare your workspace:
- Work in a well-ventilated area, as brake fluid may emit harmful vapors.
- Ensure the motorcycle is on a level surface and properly supported on a center stand or paddock stand.
Locate the brake fluid reservoir:
- The brake fluid reservoir is usually mounted on the handlebars near the brake lever. It's a small, transparent plastic container with markings indicating the maximum and minimum levels.
Clean the reservoir:
- Use a clean cloth or shop towels to wipe the area around the reservoir cap to prevent any dirt or debris from entering when you open it.
- Remove the reservoir cap carefully.
Remove the old brake fluid:
- Place the drain pan or container below the brake caliper where the bleeder screw is located.
- Locate the bleeder screw on the brake caliper. It's a small valve with a rubber cap.
- Loosen the bleeder screw using a wrench or spanner.
- Attach the plastic tube tightly over the bleeder screw, making sure it reaches into the drain pan.
- Gently pump the brake lever a few times and hold it down to create pressure.
- While maintaining pressure on the brake lever, open the bleeder screw slightly to allow the old brake fluid to flow into the drain pan. Repeat this process until all the old fluid is drained.
Refill the brake fluid reservoir:
- Clean the reservoir with a cloth or shop towels.
- Fill the reservoir with fresh brake fluid, ensuring it reaches the recommended level marked on the reservoir. Avoid overfilling.
- Recap the reservoir tightly.
Bleed the brake system:
- Starting from the brake caliper, slowly pump the brake lever a few times and then hold it down.
- Open the bleeder screw slightly and observe the fluid flowing through the tube. Close the screw before releasing the brake lever.
- Repeat this process until you see a steady flow of fresh brake fluid without any air bubbles. Ensure the fluid level in the reservoir does not drop below the minimum level during the bleeding process.
- Close the bleeder screw tightly.
Check the brake lever feel:
- Squeeze the brake lever a few times to ensure it feels firm and responsive. If it feels spongy or there is excessive travel, it may indicate the presence of air in the system. Repeat the bleeding process if necessary.
Clean up:
- Wipe off any spilled brake fluid using a cloth or shop towels.
- Properly dispose of the old brake fluid as per local regulations.
Remember, brake systems are critical for your safety, so if you're unsure about performing this task yourself, it's recommended to seek assistance from a professional mechanic to ensure it is done correctly and safely.
